Rob's more digitally savvy followers quickly took to the comments section to poke fun at the actor's gullibility, but no one trolled him quite as hard as his son, John. The 24-year-old didn't waste any time alerting his father to the fact that he'd fallen victim to a prank that he should have seen coming.

"Oh god. You literally have a son who went to Law School," he wrote in the comments section, before calling in his older brother Matthew, 26, for help. "@matthewedwardlowe come get him."

The "West Wing" star's sons Matthew and John both made their television debut when they joined their father on 2017's "The Lowe Files."

Rob has previously spoken to Insider about the idea behind the A&E reality series, which featured the trio exploring supposedly haunted locations around the country.

"It was a great way for me to spend time with my boys and go and look for stuff that we've always talked about together as a family and laughed over and argued over," the actor told Insider at the time.

"The Lowe Files" has not been renewed and aside from their TV debut, Rob's sons have largely grown up out of the public eye, with Matthew eschewing the spotlight in favor of law school and John recently graduating from Stanford University, though he has appeared in a few films, like "The Grinder" and 2014's "A Canine Affair."
